i of enclosed motor-vehicle body, and wherein a plurality of boats will be positioned therebelow for supporting the occupants and mechanism, and in whichv the riders will have much more room and comfort than theyY now have in'ordinary boats. y

Another object ofmyinvention is to provide an auto-craft of the kind described,

whichV shall be driven by air propellers, and wherein the power for driving the latter will be taken directly from the power plant of the motor-vehicle.' v

Another object of my invention is to provide a plurality ofv boats for supporting the craft upon the water and in which said boats may be manipulated so as tov guide or steer the y craft from within the motor-vehicle enclosure.

Another object of my invention is A'to provide a craft of the kind described which shall have planes or wings thereabove which may be adjustably tilted to permit the air to flow thereunder and tend to lift the craft to the top level of the water, so that said craft vwill rest but lightly upon the water and decrease the water resistance,with the consequent in- 40 crease ofspeed of propulsion.

A still further object of Vmy invention is to provide a steering rudder for such craft, and in which said rudder will not engage in the water but will extend thereabove to further increase the efficiency of the cra-ft.

Many other objects and advantages ofthe construction herein shown and described will be obvious to those skilled in the art to which this invention appertains, from the discl sures herein given.

One of the principal objects of my inven- To this end, my inventioncon'sists of the novel construction, arrangementfand combination of parts herein shown and described, and more particularly pointed out in the claims; 55

Figure lis a side elevation of my improved craft; and 60 Figure 2 is a top plan view of the same. a

Referring more particularly to the drawing, wherein l have illustrated' the preferred f embodiment'of my invention,`l indicates a base or platform ofk any suitable size, shape and material., the same being supported above the water by a plurality ofboats,fas for inf Y stance by a forward boat 2 and a pair of rear boats 3, the latter beingl located onecat either side of the platform. Struts li'may be used for connecting the platform to the rear boats,

and thef'orward boat is pivotally connected to said platform, as upon the vertical shaft l5 situata'ed` substantially centrally of the boat.

Superimposed upon the platform orbase l 5 is an vei'ic'l'osed vcab and power-generating plant, the same being obtained by the use of a motor-vehicle, preferably of the enclosed type, together with the original power plant therein. The motor-vehicle 6 is secured tight- 80 ly to the platform by any suitable fastening means and is provided with the usual doors v i? through which the passengers Vmay enter or vleave. Y

The power plant of the motor-vehiclel is operably connected to *onek or more air propellers 8 so as to be capable 'of driving the same, there being two propelle'rsshown in the drawing, one at either side of the front 9,5

of the platform. a

` Brackets or standards 9 may be mounted upon' th-e platform, and upon Vwhich the proi peller shafts 10 are journalled, said propeller shafts being connected through suitable drive r connections, as for example belts,vv gearing, 9J etc., so as to be drivenfrom the power plant of the motor-vehicle- The forwardboatZl maybe steered from i the steering wheel ill* of the motorvehicle y through/any suitable means, and =if`desired, 1.00.

the forward boat may be provided with compartments therein for the storage of oil and fuel, and from which the power-generating plant may be supplied as needed. The rear boats 3 may be used for storage of any sort, as for example of articles of clothing.

A. vertical, air engaging vane 13 may be ixedly carried by the forward boat so as to make the latter somewhat easier to steer, and

a rudder 14 may be secured upon a'vertical v "ably shaped so as to have a relatively sharp prow which enables them to cut through the i water with minimum resistance.

In order to still further decrease water resistance, I have provided front and rear wings or planes y16 and 17 respectively, said planes extending transversely across the platform and preferably being hinged or pivotally connected to their rear and forward supports or uprights 18 and l9frespectively., and I have provided means whereby said planes may be adjustably tilted so as to vary their a angle relative to the horizontal plane. This may be done in any suitable or preferred manner, as for example by permitting the forward uprights to move vertically, their lower ends having a rack thereon which meshes with a gear 20 carried upon a shaft-21, the latter being driven in any suitable manner from the motor-vehicle.

VThen it is desired-to tilt the forward ends of the wings 16 and 17 in either direction,

the shaft 21 is rotated correspondingly in the desired direction, and both wings 16 and 17 are adjusted simultaneously. These wings serve to catch the wind thereunder and as the craft travels at a relatively high speed along the surface of the water, said planes will tend to lift the craft to the top level of the water and make but light contact therewith, to thereby increase the effective speed of the craft along the water.

It may be mentioned at this point that the wings described are not intended to lift the entire craft bodily above the surface of the water as with hydro-planes, but are for the purpose of reducing the water resistance and to steady the craft in its movement through Vthe water. v

Having thusdescribed my invention, it is obvious that various immaterial modifications may be made inthe same without departing from the spirit of my invention;

hence I do not wish to be understood as limiting myself to the exact construction, form, arrangement and combination of parts herein shown or described except as necessitated by the prior art and the claims hereto appended.

Having fully described my invention, what I claim is:

1. A water-craft comprising a base a plurality of supporting wings mounted thereabove; a motor-vehicle superimposed upon said base and having afpower plant therein; an air propeller at the forward end of the V`base and driven by said power plant for propelling said craft; means for adj ustably 'tilting said wings; boats mounted below said base for 4supporting the structure thereabove upon the water; means driven by said power plant to adjustably control the simultaneous tilting of said wings; and means for steering said craft from within the motor-vehicle.

2. A water-craft comprising a platform; a steering rudder therebehind and "always entirely above saidf water; wings connected to the forward' and rear ends of said platform; a motor-vehicle upon said platform and having apower-generating plant therein ,fair propellers at the forward end of .said platformand driven by said power-generating plant to propel saidcraft; means operable by said power plant from within said 9 5 motor-vehicle for adjustably tilting said wings to vary rthe lift thereof; a pair of boats depending fromsaid platform to either side of the rear thereof; another boat pivotally connected to the forward end of said kplatform therebelow, and meansV for steering said last-mentioned boat from within said motorvehicle. l' y l y 3. A water-craft comprising a base; a plurality of wings mounted thereabove; a motor-vehicle'superimposed upon said base and having a power plant therein; air propellers at the forward end of thebase and drivenby said power plant for propelling said craft; means for adjustably tilting said wings; boats mounted below said base to support said structure upon the water and prevent the same from` capsizing; a steering DANIEL wMiCoALLUM.
